Abstract: A pressurized screen particularly adapted for screening paper making pulp includes a cylindrical screen plate mounted in a cylindrical casing and defining with it an annular chamber which receives unscreened pulp from which rejects are removed as the good pulp passes from the annular chamber through the screen plate. The axes of the screen plate and the casing are offset with respect to each other, forming an enlargement of the chamber which extends approximately from an inlet into the annular chamber to a rejects outlet which is diametrically opposite the inlet. A partition in the chamber extends parallel to the axes of the casing and screen plate from a position opposite the inlet to a position above the rejects outlet. The partition is spaced from the opposing inner and outer surfaces of the screen and casing, respectively, and a baffle is provided which extends co-extensively with the partition and slopes helically downwardly about the screen plate from the inlet to the rejects outlet and defines with the partition, the screen plate and a floor of the chamber, a passage of decreasing cross-sectional area. Inlets are also provided for adding dilution liquid to the passage upstream of the rejects outlet and a purging liquid just upstream of the rejects outlet.

IPC: B29C45/26
Filed: 1981-10-27
Abstract: A hot sprue assembly is provided for controlling flow of molten material into the mold cavity of an injection molding machine. The hot sprue assembly is particularly designed for use with an injection molding machine for molding centrally apertured record discs, such as video information discs. The hot sprue assembly includes a hot sprue bushing cooperating with a dispersion head to define an open and relatively narrow annular gate through which molten material is injected into the mold cavity, and a central die plug within the mold cavity for cooperating with the dispersion head to mold a central aperture into the disc. Valving of the molten material through the gate is achieved by heating the sprue assembly to create a temperature differential which, during soldification of the material within the mold cavity, permits the material within the mold cavity to soldify up to the gate without substantial soldification of material within the sprue assembly. The gate is disposed at a plane recessed slightly from the general plane of the soldified disc to prevent any surface discontinuities arising by retraction of the sprue assembly when the mold cavity is opened from projecting above the general plane of the disc.

Abstract: Medium-size containers with corner fittings (21) that are not in accordance with ISO specifications may be locked to ISO locking elements (25) of the type provided on loading areas of container transport vehicles by means of locking plates (10) movably disposed inside the hollow frame elements (11) of the containers, provided the container frame has a corresponding width. The locking plate (10) has an overall width that corresponds to the clear diagonal dimension of the frame element (11) and is provided on its outer longitudinal edge with cut-outs (12, 13) in the region of which the remaining width of the locking plate corresponds to the clear width of the frame element (11). For locking the container, the locking plate (10) is adapted to be moved so that one (16) of the webs defined by the cut-outs (12, 13) extends outwards through an edge hole (22) that may be formed in the frame element (11) and a further web (18) extends outwards through a corner opening (28) of the corner fitting (21). In this locking position the locking plate (10) is pivoted from its diagonal rest position so as to lie flat on the bottom of the frame element (11) and the cut-out (13) is in engagement about the locking member (25).

Abstract: A roll for use in a calender has a stationary carrier for a hollow cylindrical shell whose end portions are supported by combined radial and axial bearings surrounding annular bearing members which, in turn, surround the end portions of the carrier. The carrier defines with each bearing member a set of chambers which are sealed from the atmosphere and can receive pressurized hydraulic fluid to ensure that the end portions of the shell are biased toward a second roll with a requisite force as well that the end portions of the shell are stabilized against lateral and/or other stray movements. The fluid in the chambers ensures that the shell can be acted upon by large forces without unduly stressing the antifriction bearings. The bearing members flank a hydrostatic bearing unit which acts between the central portion of the shell and the carrier.

Abstract: Iron ore concentrate is converted to magnetic gamma hematite in an autogenous roasting operation which is self-sustaining. The iron ore concentrate is preheated and contained magnetite is oxidized to hematite. Hematite is reduced to magnetite using carbon monoxide. After cooling, the magnetite is oxidatively exothermically converted to magnetic gamma hematite. The thermal energy resulting from the latter step is recycled to the preheating and reduction steps while thermal energy resulting from the cooling step also is recycled to those steps. The magnetic gamma hematite may be subjected to magnetic separation to produce a very low silica high purity iron oxide concentrate, which may be blended with high silica concentrate to provide a pellet feed for making blast furnace feed pellets. <IMAGE>

Filed: 1995-07-28
Abstract: A digital radio communications system is presented in which the deleterious effects of fading, time dispersion and interference found in the channel are mitigated by using interference rejection and diversity combining. Digital signals representative of digital symbol sequences are transmitted through a radio channel in which the signals may be corrupted by fading, time dispersion and interference. The corrupted signals are received by a receiver having one or more antennas. The received signals are processed to form a received signal sample stream rd(kTs) for each of the antennas. Estimated received signal samples for each of the antennas are produced by combining hypothesized signal sequences and models of each channel. The received signal samples and the estimated received signal samples are processed in conjunction with an estimate of the impairment correlation properties to produce branch metrics to be used by a Viterbi, or other sequence estimation, algorithm. The branch metric processor may assume one of several configurations depending on whether or not the channel is time-varying.
